My vrs currently wears 225 / 35 / 19 tyres. Just wondering if I can change that to a 225 / 40 ? Ideally would like to drop to 18" wheels but cant afford that right now but would like to make it a bit more of a comfier ride in the mean time and wondering if this would help?

No problem at all. Plenty of space. Just upgraded from standard 18" VRS wheels on my 2019 245 to 19's with 225 35 19 and the ride is absolutely no different. 

The tyres are Uniroyal Rainsport 3's which I absolutely love, but as the sidewall is probably a little softer than the standard tyres, maybe that's the case. The handling is perfect.

Additional info

I recommend you go 235/35/19 if you are going to change the size, thicker and taller and most importantly cheaper and available in a better range of quality tyres. I run that size on my car and it’s great.

Not sure about going to a 40 height? I have gone from 225/35 to 235/35 to gain a few extra mm for ride comfort. Plenty of others have also. 

Find out if anyone is willing to do a swap if you want to drop to 18's. Cheaper than buying new tyres for your 19's and going higher profile but keeping same width is going to knock your speedo out a little as the rolling radius will change. Might even get a little cash your way as I guess for some the 19's are worth more. Personally I find the VRs 19's rather garish.

No problem dropping down to 18" ( provided you buy the correct size tyres ), but 225 / 40 / 19 would not be recommended

 

If you seach for 'tyre size comparison calulator' you'll find the 40 aspect ration takes the tyre outside the recommended tollerance.  They recommend a maximum difference in sizes to be no more than 1.5% -  you're tyre change would result in a 3.4% difference.

 

18" would definitely be the way to go. a 225x40x18 would result in only a -0.46 difference.

What size rims have you got?

 

Maybe 7.5Jx19 ET51?

 

Have a look on the back of one of the rims, as these details are always marked on. It's quite small lettering, so you may need a magnifying glass!

 

If it is what I suspect a 7.5J rim, then 235/35R19 will not officially fit because ETRTO (European Tyre and Rim Technical Organisation) says that you need at least an 8J rim for a 235/35 tyre. So a tyre fitter could refuse to fit the 235/35 size tyre to your 7.5J rim.

 

Also consider cheap steel 17" rims 6.5Jx17 ET38 from the Skoda Kodiaq. You could use 205/50R17 tyres and get a much better ride and cheaper tyres and more mpg due to less drag.

I don't think 17 inchers will fit over the VRS brake cailpers. 

Was going to say how small the difference is going from 225/35 to 225/40 because 5% of 225 is 11mm, thats 5.5 mm larger radius and while this is bigger than you get in usable tread between a new tyre and worn out, its a pretty small difference. The I read the other posts which are useful and informative. 

When I had my VRS with its patented eezi-scrape alloys I would have gladly gone to a wider tyre to protect the rims a bit.

 A Cyprus Spec MKIII Vrs has 17" wheels as standard fit. 225/45/17 on Dorado Alloy wheels. I ran a set as winter wheels on my Ex 66 plate Vrs. They are a bit tight over the front callipers but they do fit.

In the UK do they check during the MOT if you are using one of the approved/homologated tyre sizes on your car?

Here in switzerland you would fail the annual control if you didnt have one of the approved tyre sizes or e.g. you had the wrong ET of your wheels even if the difference was only a millimeter or two.

 

The official R19 sizes for the Octavia were as below I think:

    - 225/35ZR19 88Y 

    - 235/35ZR19 89Y 

    - 255/30ZR19 91Z 

R17 will also definately fit, you just have to be sure to use the modern low profile stick-on weights.

I am running R17 winter wheels on my vRS.

No. But you have to inform your insurance company if using out of spec wheels.  Some companies even ask if you are changing to a wheel that comes as an option.

When I put the 17' Winters on my Vrs I Informed my Insurance company. No extra cost but It was noted on my policy, they also wanted Informing when the 19" wheels went back on.

Minimum 15" rims with 288mm front discs

Minimum 16" rims with 312mm front discs

Minimum 17" rims with 340mm front discs

 

I haven't seen anything bigger than 340mm front discs being fitted to the Octavia as original equipment, so 17" rims should clear the front brake calipers on any Octavia.

What spacers/offset are you running? Looks mint!

 

As Sasha has said, I also recommend 235/35/19's. I replaced all of my 225 profile tyres on my 19s with 235, these fit absoluately fine and offer a little more protection. Likewise, they were £35ish cheaper a tyre than the 225 equivalent which saved a chunk. Definitely not worth cheaping out on tyres IMO. Alot of the Facebook groups have people with 235 profile tyres as well, I've never seen anyone have any issues with either fitting or running them.

Hi guys!

 

I’m a new proud owner of a 2019 Skoda Octavia VRS TDI (Estate) 4x4 DSG. 
 

I want to change the tyre size (as the roads around me are abysmal).

I believe I’m on 19” wheels and I provisionally plan to move to 245/40/R19 sized tyres to give me a bit more purchase on the road and an extra few inches between the tyre and the rim for ride comfort. 
 

Can anyone confirm if this size of tyre will fit without causing any impingement issues? 
I’ll be getting the car recalibrated for these tyres whilst some other work is being done. 
 

Cheers!

This won't work well because you're retaining 19" wheels and hence a similar sidewall height.

You'd be better to fit 17"  wheels and thus get an extra inch of sidewall.

@JackHenry Welcome.

 

Look see what size is fitted now.

Maybe while checking the tyre pressures then resetting the TPMS.

 

What sort of recalibration are you getting done if your intention is fitting tyres with a greater circumference / total diameter than on now? 

Edited 17 November, 20241 yr by Ootohere

The car has come with 225/35/R19 which I believe is the OEM size.

I’ve added a comparison chart between the 2 sizes.

 

I plan to get a dyno tune done and the gent doing it can recalibrate the car to accommodate a tyre size change for little to no extra cost. 

BS i think. 

Recalibration to suit the increased tyre size. 

 

You are looking at the wrong size.

Go a smaller wheel to get a tyre with more sidewall and even rubber on the road, and no greater circumference.

Tyres / Wheel size that will not cause you issues, including fitting and then the Type / Approval and Insurance.

+1

 

Never seen an option in the instruments to recalibrate for different rolling circumference...
